Pulmonary vein thrombosis (PVT) is a rare but potentially lethal disease. It most commonly occurs as a complication of malignancy, post-lung surgery or atrial fibrillation. Thrombi are typically detected using a variety of imaging modalities including transesophageal echo, CT-scan, magnetic resonance imaging (MRI) or pulmonary angiography. Treatment consists of anticoagulation. Here we report a...

A 61-year-old woman underwent computed tomography (CT) angiography for evaluation of syncope and was found to have a central pulmonary artery filling defect (Fig. 1). During an attempted intravascular ultrasound-guided biopsy of the lesion, the patient coded and died. Autopsy confirmed the case as a rare presentation of Rosai-Dorfman disease (Fig. 2 and Supplementary Figs 1 and 2). Supplementar...

we report the case of a three-year-old girl who complained from dysphagia and post-prandial vomiting since she was 6months old. several diagnostic work-ups were performed for her problem. upper gi endoscopy was normal but barium swallow revealed an external pressure effect over upper part of the esophagus (figure 1) and the ct angiography of thoracic aorta showed that this external pressure eff...

cardiovascular disease remains the principal cause of death in the modernized world.   several novel noninvasive imaging techniques have been recently developed to improve diagnosis of cardiac and coronary disease.   of these advances, multidetector computed tomographic (mdct) angiography has evolved most dramatically to transform computed tomography from a single-slice trans-axial modality to ...

introduction: pulmonary involvement secondary to systemic sclerosis (ssc) is the major cause of morbidity and mortality in ssc patients. we designed this study to determine the correlation of important lung function parameters with lung high resolution ct (hrct) scan findings.materials and methods: thirty–two consecutive diffuse ssc patients with pulmonary fibrosis were enrolled in this cross-s...

BACKGROUND The aim of this study was to determine the optimal monochromatic spectral CT pulmonary angiography (sCTPA) levels to obtain the highest image quality and diagnostic confidence for pulmonary embolism detection. METHODS The Institutional Review Board of the Shanghai Jiao Tong University School of Medicine approved this study, and written informed consent was obtained from all partici...
